Application tiled May 20, i918.V Serial No. 98,855.

To all whom it may concern.'

Be it known that l, ARTHUR L. SHAW, a citizen of the United States, residin at Chi# cago, in the county of Cook and tate of Illinois, have invented certain normand useful Improvements in Conveyers, of which the followin is a specification.

My inventionrelates to improvements in conveyors and more especially to portable conveyors of the chain and drag type.

One of the objects of my invention is to provide certain improvements in the general construction of portable conveyors and also to provideepecific improvements in the details of construction to adapt the con veyer to rough usages, as when loading and unloading wagons, cars, ships, and the like, and especially when handling coal, stone, ore. and such other rough material.

'lhe embodiment of my invention, as illustrated in the accompanying drawings, is devised more especially for loadinfr and unloading coal, from and into rail-way cars, and such like uses, and is especially adapted to be shifted from car to car, along the sidetrack of a railway, upon a suitable overhead trolley track, to be erected parallel with such a railroad track, by means of an over-running trolley and connected pullev block. The subject matter of the trolley and support is claimed in an application Serial No. 98.856 which l[ have tiled ot even date herewith.

The principal features ot novelty ot this present invention resides in thegeneral form, arrangement and coperation ot the parts as hereinafter more specifically pointed out and claimed.

Other and further objects of my invention will become readily apparent, to perscns skilled in the art, from a consideration of the following' description when taken in conjunction with the drawings, wherein Figure l is a side elevation of the conveyer, with parts broken away to show some of the power transmitting machinery.

Fig. 9 is a transverse section taken on line 9-9 of Fig. 6.

In all thc views the same reference characters are employed to indicate similar parts.

The conveyer comprises, a sub-frame 10 and a superimposed frame, or trough 11. rl`he sub-frame 10 consists of two parallel angle bars 12-12 inturned with one leg of each placed in a vertical plane, as at 14. The angle bars are bent at an angle, as at 15, whereby to gradually in crease the distance of separation between the sub-frame and the trough to provide `space for the driving machinery and to thereby decrease the vertical dimensions of the terminal ends of the conveyor, as well as to decrease the weight of the machine and add to its strength and convenience of its use.

At suitable intervals the angle bars 12v are connected with the longitudinally extending trough 1l by means of vertical posts, preferably angle irons, with one leg thereof in contact with the outer surface of the frame members 12 and with the outside surface ot the trough and the other leg in a horizontal plane and extending inwardly, as shown in the drawings. Posts 17 to 21 inclusive are located on one side of the structure and corresponding posts on the opposite side thereof. A cross bar 22, which preferably is an angle iron, connects the pair of posts 18 together, and is located in the space between the sub-frame and the trough, sufficiently elevated above the sub-trame to permit the drag chain to pass thereunder and in the same manner pairs of posts 19, 40 and 20 are connected by bars 23, 24 and 25, respectively, which are located substantially the same distance above the sub-frame. By locating these cross connecting bars above the members l2 ot the sub-trame, instead ot putting them on the lower surface thereof, the delvice, as a whole, may be moved over the ground or over any other sappen` ...sa

in its structure without encountering the resistance that would otherwise be offered by these cross bar projections.

An angle bar 26, on each side of the frame, is secured to the upright posts 20, and 21, and projects rearwardly from the latter post to provide a .support whereupon to mount the bearings 27 for the transversely extending power shaft 28. The shaft 28, at the rear end of the device, carries a air of sprocket Wheels 29 for the pair of rag chains 30. At suitable intervals, and by proper means, the drag chains 30 are connected together by transversely extending bars or drags 31. These drag bars or scrapers are moved forwardly in the trough 11, as in the direction of the arrow, as shown in Fig. 1, to carry material that may be deposited within the trough at the rear, to the front end of the machine. Projecting from the front end of the machine and secured to the vertically extending posts 17 -are a pair-of stirrups 32 for carrying the bearings 33 that support the transversely extending driving power shaft 34. Separated a suitable distance apart, on the shaft 34, are a pair of sprocket wheels 35, around which the drag chains pass, and by which they are driven. For the purpose of manufacture the sprocket wheels 35 are preferably duplicates of the sprocket wheels 29 located in the rear of the conveyer. Mounted on the shaft 34 is another sprocket wheel 36, preferably somewhat larger in diameter than the sprocket wheel 35, and serving as a means for driving the shaft 34 through the instrumentality 0f a drive chain 37.

A chain guide, consisting of a pair of angle irons 38 each connected on each side to the posts 20, 39 and 40, are so placed that their vertically extending legs are connected to the posts and the laterally extending legs project inwardly above toward the transverse center of the conveyer, as shown in Fig. 4, and under which latter legs the chains 30 are moved. At the point 41 the angle bars 38 are deflected upwardly at an angle of about 15 degrees from the horizontal, as shown atl 41, to provide a base upon which to secure the electric motor 42, or other motor that may be used for driving the drag propelling mechanism. When the front end of the conveyer is elevated to a higher altitude than is the rear end, which is frequently the case when the device is being used, especially when loading or unloading cars, the angle of the motor base is s`uch that the' motor will be in a substantially vertical upright position.

Connected to the angle bars 38 is a plate 43 to support the motor, and which extends transversely of the conveyer and is one means which contributes toward holding the members of the sub-frame together.

On. the motor shaft 45 is a pinion 46 which meshes in a relatively large dian'leter gear wheel 47. The wheel 47 is fixed to an intermediate shaft 48 that extends transversely of the conveyer. On the other or remote end the shaft contains a pinion 49, substantially of the saine dimensions and character as the pinion 46, which meshes into another gear wheel 50, which is substantially a duplicate of the gear wheel 47. and which is secured to the outer end of the transversely extendingl driven shaft 51. To the outer end of the shaft 51 is connected a driving |sprocket wheel' 52, which is substantially a duplicate of the gear wheel 36 located at the front end of the machine, and between which and the gear wh'eel 52, the drive chain 37 is connected. The posts 39 and 40, upon which the aforesaid train of gearing is supported, each consists of an angle iron, each having a part of the inturned leg cut away, so that the remaining leg may extend further and make fiat connection with the outer surfaces of the frame members 12 and the guard members 38, and with the outside surface of the trough 11, as at 53. The inwardly extending legs 54, of the posts, are sufliciently long to rest upon the guard rails 38 and vto support the outside edges of the trough 11. The bearings 55 and 56 for the shafts 48 and 51, respectively, are connected to the inner projecting legs of the posts 39 and 40, respectively.

The trough 11 rests upon and is secured to angle iron cross bars. 53` which are in turn {ixed to the pairs of vertical posts that hold the trough and the sub-frame together.

A shield for the motor and the train of gearing required to transmit the power therefrom to the driving chain 37, is coniposed of plates 59 that are secured between and to the posts 20 and 40, one on each side of the machine.

A strap 60 is secured to the bottom frame members 12 and to the trough 11, to which a bail 61 is pivoted. These straps are located on the frame at points whereby the machine will be substantially balanced, so that it may be easily and .conveniently handled by means of the bail.

At the rear end of the conveyer, the pairs of posts 2O and 21 are extended higher than the side walls of the trough 11, proper, and side-boards or plates 62 are secured to the respective posts to make the trough at these points deeper, to prevent the material that may be shoveled into the conveyer from falling out or passing over the upper edges of the trough.

Pivotally secured at the rear near the upper surface of the plates 62 is a trap. or valve plate 63, as at 64. This trap late automatically rises and falls when the dings 31 pass under it. The object of the plate 1s naaaaaa W to retain the material in the trough when the front end of the conveyer is elevated to a higher altitude than is the rear end.

An apron 65 is placed under the ioor of the trough ll*V and extends between the sprocket wheels 35-35 that carry thechains 30-30 to protect them from the coal that would otherwise fall Vfrom the end of the trough into chain linls. The apron 65 eX- tends forwardly beyond the shaft Bfland is curved at its front end upon about tle same radius as thepitch diameter of the sprocket wheels 30. Another apron 66 consisting of the attached dished ends 67 and the curved intermediate portion 68 is provided with angularly positioned ends 69, separated substantially equal to the width of the trough l1( llFhis apron is provided with a foriwardly projecting flange 70 perforated, as at 71, by which it may be. secured to the angle bar 58 by the rivets 72. rllhese rivets also serve to secure the apron 65 in place, as clearly shown in'Fig. 7. i The aprons 65 and 66 direct the coal into the attachable chute 73 which issecuredgto the conveyer by hooks 74e. rllhe floor 7 Sbf the chuteis perforated, as at 75, to receive the hooks. .i

By placing the Iotor and a train of gearing between the sub-frame and the trough, they are protected against damage that may result from collision with othervobjects in handling the conveyer and the operatorand other persons are protected fromdanger that may result from Contact with theV gear wheels whlle they are inmotion:
